To all whom it may concern Be it known that I, Tnnonon Sumxx, a

citizen of the United States, residingatBarberton, in the county ofSummit andState of Ohio, have invented certain new and usefulImprovements in Rotary Engines, of which the followingis aspecification.

This invention relates to rotary engines adapted for operation by motivefluid of various kinds. It is particularly applicable to rotary enginesof the type having a swinging abutment, and this abutment also serves tocontrol the inlet of the motive fluid to the cylinder.

In the accompanying drawings Figure 1 is an end elevation of the engine;I

Fig. 2 is an end elevation withthe end plate removed;

Fig. 3 is a cross section showing the parts at the intake position;

Fig. 4 is a similar view with the parts at the exhaust position;

Fig. 5 is a section on the line 55 of Fig. 1;

Fig. 6 is a section on the line 6-6 of Fig. 3;

Fig. 7 is a section on the line 7-7 of %n the drawings, 1 indicates thecylinder in which the rotor 3 is mounted, and adjacent this cylinder isthe abutment casing or extension 4: in which the abutment 5 is mounted.6 is an end plate coveringone.

end of the cylinder, and 8 is a reinforcing rib for the periphery of thecylinder.

The rotor or piston 3 comprises a central hub 10 through which the driveshaft 12 extends. Extending outwardly from the hub is the rim or body 13of the rotor which is substantially T shaped in cross section. Grooves14 are made in the sides of the rotor to receive the flange 15 or thebushing plates 16 which are held by the screws 17, and packing rings 18are placed in corresponding circular grooves in the bushing plates 16which are inclosed within the end plates or cylinder covers.

The rotor 3 has two projecting wings 19 the front faces of which aretangent thereto as indicated at 21 and the rear faces of which arerecessed as indicated at 20. These wings turn in contact with thecylinder wall.

The abutment 5 comprises an outer knuckle 22 having trunnions '23mounted in bearings 2 1 in the extension on the cylinder Specificationof Letters Patent.

referred to. Extending from knuckle is a plate or part 25 which swings.into and out ofthe cylinder and is provided with a roller 26 whichrides on the face of the rotor and its wings. The inlet pipe 41 istapped into the projection on the casing and is adapted to communicatethrough a port 410 with a passage 33 in the abutment, said passageleading to the space within the cylinder.

A screw 27 is provided to limit the inward swing of the abutment and tocushion the outward swing a pin 30 is provided which works in a recess29 in the abutment and is supported by a spring 31 under the head 32 ofthe pin and this head is adapted to strike the wall of the extension 4;when the abutment swings out.

The body of the extension 4: is bored through as indicated at 34*, andslotted as shown at 35 across the knuckle joint, giving suflicientspring to enable the wear on the bearing of the lniuckle joint to betaken up by tightening the stud 36.

The bore or hole 29, in which the pin 30 works, communicates at itsinner end with the intake passage 33, and when the pin is forced by theoutward swing of the abutment its inner end crosses and closes thepassage 33, as shown in Fig. l, and opens said passage when the abutmentswings in wardly, which action is assisted by the spring 31.

In operation, with steam or the like the fluid enters from the supplypipe 11 through the passage 33- when the parts are in the position shownin Fig. 3 and drives the rotor until the wing 19 lifts the abutment,thereby closing the passage 33 as shown in Fig. 4. Exhaust takes placethrough the opening 42 in the cylinder wall and the operation continues.

The bushing plates 16 and rotor 3 are cooled through openings 45 cut inthe end plates 6 of the casing.

The invention thus provides a rotary engine capable of operation bysteam, compressed air or other fluid and the swinging abutment acts toautomatically control the inlet of the motive fluid, without thenecessity for any exterior valve mechanism.

I claim:

1. In a rotary engine, the combination with a swinging abutment having apivotal knuckle, of a casing forming a bearing for the knuckle and splitat one side thereof,

and means to spring the parts together to take up Wear.

2. In a rotary engine, the combination with a cylinder casing and arotor therein, of a swinging abutment pivoted in the wall ofithe cesingand provided with an inlet oassa e and an inlet ort in the czisin b 7 7adapted to be registered with said passage by the movement of theabutment, a pin mounted in the abutment with one end in v 1.11,testimony whereof, I do aflix my signatnre in presence of twowitnesses.
